Limit value configuration
8.7.3
Switch-on delay limit 3 (empty)
Switch-on of Limit 3 (empty) can be deliberately delayed by a delay time (ms). This is helpful,
for example, if the weight is undershot at the moment of opening when the scale is being
emptied, which would cause Limit 3 to be fallen below already.
8.7.4
Limit 3 - empty
This parameter defines the time starting from which the scale is empty. The unit is expressed
either as a percentage of the maximum weight or in the weight unit depending on the "Limit
reference" setting Unlike Limit 1 and Limit 2, Limit 3 always references the gross weight of
the scale.
